Answer:
]-inf, inf[, or (-inf, inf), or {x|-inf < x < inf}, or R, or the set of all real numbers.
Step-by-step explanation:
If not limited specifically, all polynomials (of which y=3x^3+4x^2 is one) have domain (-inf, inf), or in set-builder notation, {x|-inf < x < inf}
Answer:
5 and 13
Step-by-step explanation:
To evaluate (w ○ u)(8) , evaluate u(8) then substitute the value obtained into w(x) , that is
u(8) = = 8 + 9 = 17 , then
w(17) =
=
= 5
---------------------------------------
To evaluate (u ○ w )(8) , evaluate w(8) then substitute the value obtained into u(x) , that is
w(8) =
=
= 4 , then
u(4) = 4 + 9 = 13
The answer to 17 is 18.6 and the 6 is repeating
Answer:
The margin of error M.O.E = 2.5%
Step-by-step explanation:
Given that;
The sample size = 1500
The sample proportion
= 0.60
Confidencce interval = 0.95
The level of significance ∝ = 1 - C.I
= 1 - 0.95
= 0.05
The critical value:
(From the z tables)
The margin of error is calculated by using the formula:




M.O.E = 0.02479
M.O.E ≅ 0.025
The margin of error M.O.E = 2.5%
Let's try to find some primes that divide this number.
The number is not divisible by 2, because it is odd.
The number is divisible by 3 though, because the sum of its digits is:

So, we can divide the number by 3 and keep going with the factorization:

This number is again divisible by 3, because

We have

This number is no longer divisible by 3. Let's go on looking for primes that divide it: 5 doesn't because the number doesn't end in 0 nor 5. This number is not divisible by 7 or 11 either (just try). It is divisible by 13 though: we have

And 557 is prime, so we're done. This means that the prime factorization of 65169 is
